Abstract: PURPOSE: A valve for a muffler is provided to completely remove the noise occurring due to the contact of a valve plate and a valve supporting member by installing a contact noise preventing member. CONSTITUTION: In the case of a valve(100) for a semi-active muffler, a valve plate(110) opens and shuts off a central hole(121) of a valve supporting member(120) when exhaust gas flows into chambers. Then, a hanging portion(115) of an inducing portion(112) of the valve plate contacts to a sidewall(126) of a settling portion(123) of the valve supporting member. The noise occurring due to the contact is reduced by a contact noise preventing member(150) installed on the sidewall of the settling part. Since the contact noise preventing member is made of a wire mesh, elasticity is maintained and the contact noise is absorbed by the elasticity. The wire mesh member is composed of stainless steel so that durability and corrosion resistance are maintained.
